Nobunaga Ramen in Tokyo serves chicken-broth ramen and tsukemen. The noodles are chewy and hand-made, and the broth is rich chicken stock, served with a soft-boiled egg, green onions, and lemon. Orders are placed at a kiosk, and the spicy level leaves a slight tingle on the lips while the chicken comes out tender. The broth's color is unusual and may be off-putting at first.
